DNA extraction procedure

Lysis
1. V tubes obemom 1,5-2 mL place issleduemye samples. V sluchae khraneniya obraztsov v fiziologicheskom rastvore tsentrifugirovat samples v techenie 5 minut pri 13 000 ob/min, posle chego polnostyu udalit supernatant.
2. Add 450 uL liziruyushchego bufera, 20 uL Proteinazy K i 2 uL Stabilizatora.
Optsionalno: vozmozhno ispolzovanie RNAazy A lyubogo proizvoditelya v kontsentratsiyakh, rekomendovannykh proizvoditelem.
3. Incubate samples v termostate pri 60℃ ne menee 3-x chasov. Rekomenduetsya inkubirovat samples v techenie nochi dlya bolee polnogo lizisa tkani i bolshego vykhoda NA.
4. Perenesti tubes na led ili v kholodnyy shtativ i inkubirovat v techenie 1 minuty. V sluchae otsutstviya okhladitelnykh elementov inkubirovat at room temperature v techenie 5-10 minut until completely cooled smesi.
Nucleic acid sorption and precipitation
1. Add k smesi 75 uL osazhdayushchego bufera 1.
2. Intensivno peremeshat tubes on a vortex mixer, sbrosit kapli s pomoshchyu brief centrifugation.
3. Incubate v techenie 3-5 minut vo ldu ili v cooling rack. V sluchae otsutstviya okhladitelnykh elementov inkubirovat at room temperature v techenie 5-10 minut.
4. Centrifuge tubes v techenie 5 minut pri 13 tys. ob/min.
5. Akkuratno, ne zadevaya pellet, perenesti 500 uL supernatanta v novuyu tube obemom 1,5-2 mL.
6. Add 500 uL osazhdayushchego bufera 2 i peremeshat s pomoshchyu pyatikratnogo perevorachivaniya tubes.
Optsionalno: dlya uvelicheniya vykhoda DNA rekomenduetsya inkubirovat samples v freezer pri -20℃ v techenie 25 minut.
7. Centrifuge tubes v techenie 5 minut pri 13 tys. ob/min, posle chego udalit supernatant, ne zadevaya pellet.
Nucleic acid washing
1. Add v tubes 700 uL promyvochnogo bufera 1.
2. Intensivno peremeshat tubes on a vortex mixer.
3. Centrifuge tubes v techenie 5 minut pri 13 tys. ob/min, posle chego udalit supernatant.
4. Add v tubes 700 uL promyvochnogo bufera 2.
5. Repeat punkty 2,3.
6. Vysushit samples s otkrytymi kryshkami v termostate pri 42℃ ili v tsentrifuge-kontsentratore pri 30℃ until complete ispareniya promyvochnogo rastvora.
Nucleic acid elution
1. Add v tubes 50-100 uL elyuiruyushchego bufera.
2. Incubate v termostate pri 55-60℃ v techenie 5 minut, periodicheski peremeshivaya on a vortex mixer.
Poluchennye rastvory nucleic acids can be stored do 7 dney pri temperature ot +2℃ do +4℃ i do dvukh let pri temperature -20℃. Po absorbance ratio na A260/A280 purity of the resulting solution DNA ≥1,7.
